RAIL-BOLT-NUT ADJUSTER.

Specification of Letters IPatent.

Patented July 23, 1907.

Application filed June 3,1907. Serial N0. 377,026.

To all whom it may concern:

Be it known that I, HENRY SMILEY, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have made a certain new and useful Invention in Rail-Bolt-Nut Adjusters; and I declare the following'to be a full,

clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specilication.

Figure l is a perspective view of the invention. Fig. 2 is a side view partly broken away of the invention'as applied for adjusting a nut and washer. Fig. 3 is a similar view of the invention as applied for adjusting a nut, the holding arm being turned aside, out of the way. Fig. 4 is a central longitudinal section of the tool. Fig. 5 is a side view of the same, with parts separated as in use. Fig. 6 is a front view of the same, the holding arm beingv shown as turned to one side out of the way. Fig. 7 is a detail perspective view of-one end portion of the lever dev ice, Fig. 8 is a similar view of one end portion of the holding arm. Fig. 9 is a front view partly broken away of the invention as applied.

The invention relates to a rail-bolt nut adjuster, especially designed for use in connection with the sections of stairway rails or balustrades.

The invention consists in the novel construction and combinations of parts as hereinafter set forth.

In the accompanying drawings illustrating the invention the letter a, designates the sections of the rail to be connected, such sections having the usual openings or recesses a, in the bottom adjacent to the joint thereof, and b, is the rail-bolt having threaded end portions carrying, cach a nut c, having a washer cf.

d, designates the tool, having'the handle portion d, and the nut-carrying flattened shank portion d2, provided at its outer or upper end with a right angle cylindrical stud e, upon which "the nut is slipped. For the purpose of adjusting this nut laterally after it has been .inserted into the recess a, of the rail by the tool, a lever device f, is fulcrumed to the handle portion d', of the tool at b/, this lever device having a bifurcatedF or forked end portion g, the arms of which lie at each side of the carrying stud e, such arms being offset laterally or of greater thickness than the web g, connecting the same. The lever f, is, also of flattened form, the work arm thereof normally lying in close contact with and having similar dimensions to the shank portion d2, of the tool with the exception of the arms of the fork g, which project laterally of such shank and are offset or of sufficient thickness to normally embrace the same. This lever device has an intermediate enlarged head portion h, shown as of cylindrical form and forming the inner end portion of the work arm thereof,l the power or operating arm t', of the lever being tapered from the fulcrum thereof and seated in a slot fi, of the handle end of thetool with the side walls oi which the fulcrum pin engages. The side walls of the slotted portion of the handle are cut away or notched at j, to admit of finger pressure upon the operating arm of the lever, which is thus caused to move to one side away from the shank of the tool, carrying therewith the nut upon the stud el v c, designates a holding arm pivoted at one end thereof to a Istud pin IM, of the head h, and having an intermediate laterally offset portion t, constituting the greater portion of its length and normally lying in close contact with the work arm of the lever f. This holding arm has a Aforked outery end portion h2, having the same level or lying in the same plane as its pivoted inner end portion, and the arms of which lie at the sides of the stud e, being separated from the nut upon such stud by an interval sufficient to allow for the reception of a washer upon such stud, with which the arms of the fork are designed to contact.' In this manner the nut and washer therefor lie between the forked end portions of the lever device f, and of the holding arm lc, which forks are separated from each other just the thickness of nut and washer, and upon lateral ad; justment of the lever device by finger pressure upon its operating arm, nut and washer are at the same time adjusted to position upon the bolt. In order that the adjustment may be in direct line with the bolt, the inner end of the stud e, is concaved to provide a seat at a for the rounded inner end of the bolt. The nut may be in this manner adjusted squarely in position upon the bolt, and upon insertion of a screw driver or other slender tool, the nut may be given a whirl upon the bolt to cause it to be turned home upon the thread thereof.

The head portion h, of the lever f, has a semicircular wail l, at one side terminating at one end in a square shoulder Z, and at the other end in a beveled shoulder Z2. The circular pivotal end of the holding arm 7c, lies upon this head portion of the lever with its squared shoulder normally in contact with the shoulder Z/ of such wall forming a stop for the holding arm when in line with the shank of the tool.

To facilitate placing the nut, or nut and Washer, upon the stud c, the arm lc, may be turned to one side upon its pivot, until the beveled shoulder n, at its inner end contacts with beveled stop shoulder L2, of the head h, of the lever. In order` to provide tension adjusting means for this holding arm, a washer o, having a square central hole engages a squared portion o/, of the stud pin hf, a nut p, engaging the threaded end of such pin and having frictional contact withrthe washer o, which on its under side contacts with the pivotal end of the Oholding arm. The holding arm is not needed to be used When the nut alone is to be adjusted to position upon the bolt, but is provided to hold nut and Washer together When both are to be adjusted to place.

A coiled spring q, is located beneath the operating arm of the lever f, between the same and the bottom of the slot in the handle of the tool, such spring engaging projections upon lever and handle to keep it in position. In this Way, the parts are automatically returned to normal position, where they will be held by the spring.

A safety catch device r, is seated ,`in a recess oi the handle of the tool and normally projects underneath the operating arm of the lever f, to prevent its accidental operation or depression. A knob projection 7, upon this catch device enables it to be readily shoved back by the thumb or nger out of the Way, against the pressure ol its coiled spring r2, which causes it normally to project.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A rail-bolt nut adjuster, having a shank portion provided with a stud at its outer end, and a'lever device having a forked end portion, the arms of which normally lie at each side of such stud.
